RE: [lwip-users] Observations about lwIP on a Xilinx Virtex 4

[Matthew Yingling]

You should be able to view the xemacif.c file in the v2pro/netif folder of
ports in the CVS repository.  It's up to date with the current LwIP API, I
believe, and it should be pretty obvious how to update your driver.  It's
mostly some minor return values that change.
